QCS (Quest Collaboration Services) keeps loosing MAPI connectivity to the service mailbox -
说明
The following errors are reported consistently in the QCS Events Log with the specific time interval:
![2009/10/16 13:25:27.846] (2) Warning :<Exchange Layer> (32622) Error occurred while retrieving data from the Exchange server. [0x80004005 (Unspecified error)
MAPIServ.log contains the following entries corresponding to the above events:16/10 13:25:21:194 | 364 |Error: Unspecified error 0x80004005

原因
If FBSender.log is examined it may be noticed that QCS is failing on access to specific Schedule + F/B Public Folders:
16/10 14:43:29:624 | Collector.cpp(635) | 6040 | Incompleted cookie. Folder name: EX:/o=TEST/ou=EMEA16/10 14:43:34:671 | Collector.cpp(645) | 6040 |Error: Unspecified error 0x8000400516/10 14:43:34:671 | Collector.cpp(635) | 6040 | Incompleted cookie. Folder name: EX:/o=TEST/ou=APAC
16/10 14:43:41:874 | Collector.cpp(645) | 6040 |Error: Unspecified error 0x80004005
The same can be reproduced with MFCMAPI when logged with QCS service account into its mailbox:MAPI application will fail on access to the above mentioned folders. -
解决办法
Please ensure all F/B folders through the entire Exchange organization are accessible. In some complex Exchange environments there can be obsolete Schedule + F/B folders that represent old renamed/retired Administrative Groups which no longer have any replicas. Because their configuration information is still present in AD, QCS will still try connecting to them since its designed to enumerate all F/B folders. Please remove such folders or create at least single replica. Be careful - sometimes obsolete F/B folders may actually have replicas and contain production F/B data - refer to Microsoft resources for more assistance.
For the better F/B synchronization performance, all Schedule + F/B Public folders need to be replicated to the Exchange server where QCS service mailbox resides. -

Note: Occasional QCS Errors 32622 are normal, as long as they are not persistent
